An automatic waterer which utilizes a self closing valve which is vertically installed and in which spring and hydraulic pressure work to seat the valve and in which a pivoted beam which utilizes a weight of substantial mass at one end and which carries a drinking bowl on the other end is provided. As animals drink from the bowl the mass overcomes the weight of the liquid in the bowl and lowers the beam on the valve actuator so as to replenish the liquid supply in the bowl thus rebalancing the beam and allowing the valve actuator to return to the closed position.
